To ctll'ivhmn it may concern: j

Be it known that I, JOHN M. HALL, of War renton, in the county of Warrenand Stateof Georgimhave invented a new and Improved Rotary Hoe for thepurpose ot' chopping' outV cotton, to be worked by-horse-power; and

' do hereby'declare that the ibliowingis a full its construction andoperation.

To an ordinary Wheel I atl-ach a bevel-gear Wheel of such diameter andnumber ot' teeth as shall,whena cting upon the bevel-pinion on thehorizontal shaft of the hoe, give the requisite number ot' chops or cutsto each revolution of l the carriage-wheels. I Vconstruct my carriagewith two Wheels and an axleofsuliicient length 'to give a distancebetween the wheels of not loss than that between the rows of cot-ton,curv.

v ing the axle downward sutcient to allow the horizontal shaft to be onaline with of the wheels.

Attached to the axle are bars extending suf!` ticiently back of the axleto receive the bearings ot' the-journals Vof the horizontal shalt. Tothese bars, which are on. the front bent into a goose-neck shape, areattached thel shafts for the center 'the horse, in such a manner that'he shall not walkl on the rows.-

From the front of'thecarriage, and secured by braces from the axle,fis ahandle, b, to guide the carriage on uneven ground.

On the 'end of the horizontal shaft l attach my hoewheel, the face ofthe hoe-wheel being of suicient breadth for 'the size and number of hoesemployed. The shanks of the hoes are made of iron, the cutting pai-t ofsteel, and are y securedto the wheel by two bolts each.` The holes inthc shanlis of the hoes are made from one to three inches in length, inorder to regulate the depth ofthe cut into the ground. The holes in theface of the bolt are, one the size ot' 4the. holt, and the other fromtwo to three inches in len gthldiagouall y across the fac-cot the wheel,to regulate the angle of the cut and unequal wear ofthe hoes, as is morefully shown by the drawings accompanying this specication, in which-.

No. 1, Figure l is a view of the hoe, with one wheel of the. carriagetaken ofi, the better to show all the parts. a is the shafts to whichthe horse is attached; c, the hook to which is .attached the whifetree;d, the carriage-wheel,

to which is bolted the bevel-gear wheel fro, that imparts the rotarymotion to the horizontal shaft H H by means of the bevel-pinion u, andto the hoe-wheel P and hoes t t' i, by the forward motion ofthe'carriage, thereby causing the hoes" toenter the ground at` regularintervals; S S, the boxes or bea-rings for thejournals of, thehorizontal shat't H H; e e, the axle otA the carriage; m, the iron barssecured to the axle, on which rest the bearings'for the journals ot' thehorizontal shaft, and to which are attached the shaftst'or the horse 5'b, the guiding-handle, sccuredbythe braces a: to the carriage. t i

Fi'g. 2 is' an enlarged View ot' one of the hoes i detached from thewheel, showiiig its form, and the holes or slots r o' r fr in the shankof thehoe for changing the depth of the cut.

Fig.' 3 is a sectionhor4 portion 4of the face of the hoefwheel P,showing the manner by which the angles of thehoes are changed', and theunequal wear ofthe `hoe overcome by means ot'` the diagonal slot 1.

What I clainras my invcntiomaud desire to 4secure by Letters Patent, is-

In com bination with the wheel P, the adjustable hoes:17,t`constructed,arran ged, and operating in the manner and for 'thepurpose set forth. i y JOHN-M. HALL.
